invention has for its object animprovement in the means for securing remov able VdhlClGWhGGlS to a hub .m'the case where they are secured by means of spindles passing on one hand through the wheel and on the other through a part integral with the hub. This improvement applies as well to] the case of simple wheels asto that of twin wheels.

Thespindles used heretofore for securing wheels to a hub are generally constituted by a rodthreaded throughout its length or over a partgthereof and provided with a basis adapted to bear against the outer surface of the hub flange. The spindle is secured throughthe agency of a nut which is screwed" over. its inner end."v Whenever; the spindle breaks, it breaks generally-in the part be-1 tween the basis of the spindle and the nut 9, locking the wheelwhich is fitted over the outer end of the spindle. Consequently for I Now I remove these drawbacks-according to my invention, by replacing the nut which was'heretofore carried by the inner end of of the hub.-to which the wheel'is secured. This ring may be secured in any suitable 4 manner to the hub, for instance through into it, it is'possible to holdit stationary in any suitable manner, for instance .by means of an inner or outer stud; 1 It is easy to understand that if the spmdle werejto break in such; an arrangement,

l it is suflicient to takehold of'the basis which the spindle by an inwardly threaded ring adapted to engage a part, such as the flange.

screwing, forcing, riveting or the-like. The

may be providedwith notches therefor and to unscrew it whilemovingit outwardly.- It

is no longer necessaryto gain access to the inside of the hub which is difficult and often impossibleto achieve without removingthis 5 The method and device according to my invention should not be compared withthe known mounting accordingto which the axis is simply screwed into the flange of the hub.

As a matter of fact, thisarrangement'shows the serious drawback of requiring animportant and very costly repair (generally the completereplacement. of the hub) whenever the thread provided directly in the flange off5 the hub is, damaged. On the; contrary, in

the arrangement according to myinvention, the ringmay bechanged with the greatest ease without requiringany great expense. 7

Further advantages of mv invention will appear from the following description of my invention. a V

Appended drawing shows by way of example acertain number of: forms of execution whichwill allow 'my invention to be better understood. f-

Fig. 1 is a sectional View of part of a hub flange provided with a ring according tofmy invention and of part of the spindle used 7 for securing a single wheel. v

Fig. 2 is a cross-sectional view of a modi fi cation of my invention adapted for mounting twin wheels. V l

Fig. 3 shows the invention as applied to a very thick flanges i Fig. 4 shows it as applied to'a double flange. I l r Fig. 5 illustrates a further application of my invention. 1 i In Fig. 1 of thedrawing the hub flange is shown at 2 and the spindle'provided with its usual basis 4 at 1. b The spindle is secured inth-is case by means ofa ring 7 engaged by the flange in any suitable manner for instance 1 through screwing, forcing, riveting or the 7 like. Before screwing the spindle 1 in" this ring, the latter is prevented from rotating with reference to the flange 2 by means of a projection or stud 8 which is caused to engage .100

the flange and the ring from the outside of the hub. i

It is apparent that if in this case, the spindle breaks to the left of the basis 4, nothing is easier than to remove it outwardly. The basis 4 may be provided to this end with suitable notches allowing an easier grip to be exerted on it.

In Fig. 2 is shown a flange 2a to carry two twin wheels. also for carrying the brake drum 9. The spindle 1a shownqin Fig. 2 is provided, b yond its basis, with a washer having a special adapted shape which serves to center the first twin.

wheel. i

In this case as precedently the inner end of the spindle is screwed into a" ring 7 according to my invention. In the example illus trated, the ring is held against rotation by a stud 8 which is caused to engage the ring from the inner side of the hub.

It is apparent in the case ofF'ig. 1 that the.

spindle passes entirely through the ring and projccts slightly with rcference to the inner; surface of the latter.

In the case of Fig. 2, the spindle does not reachv the inner surface of the ring. It is easy to understand that in both cases, the spindle is held perfectly tight; This is'of particular advantagein the case where the thickness ofthe hub flange is considerable.

An arrangement of this type is illustrated in wherein the flange 2b is very thick. In this'oase the ring 7 is given asuitable length whereas on the contrary the spindle 1 has the same length as in the preceding cases without any drawback arising therethrough. i

This feature shows a considerable-advantage owing to the fact that it allows spindles of the same length to be used whatever the thickness of the hub flange'inay be. i

In Fig. 4, I have shown at 12 a flange of a special type. It is a double flange and comprises beyond the usualiipart 10; a second annular part 11. In this case. the ring 7 cannot be inserted from inside the hub as: in the case of the preced ng figures. Consequently the ring has to be inserted from the outside of the hub. It canbe held place through the agency of a nut 13'. i

In Fig. 4 is shown a spindle of a particular type which can be used with thering according to my invention. This spindle. is characterized, by its smooth end 14. the diameter of which is smaller than that of the threaded part of the spindle. The ring? is also provi-ded with an extension 15' the diameter of which corresponds to that of the non-threadedpart of the spindle. t

This manner of mounting provides a better centering of the spindle.

In Fig. 5, I have shown the manner of mounting twin wheels according to which the flange 16 is provided with the brake drum This flange serves forded by my invention are numerous. The

most important are those relating to the easy removal of the spindle allowing its easy and speedy replacement. Moreover it is easy to use spindles of constant length whatever the thickness of the hub flange'maybe. Lastly'the space available inside the brake drum is used to the utmost owing to the omission of the nuts which are replaced by a cylindrical portion of the ring, the thickness of which is i very reduced. Moreover if the method of mountingaccording to my inventionis compared Wlth' the known method of mounting consisting insimply screwing the spindle the flange, it isapparent that the drawbacks. due to. normal or. fortuitous wear of the threadprovided in theflange or in the: brake drum are reduced to a What I claim is: r

1. In a vehicle wheel, the combination of a hub flange provided with at. least one hole close to its periphery", an inwardly threaded sleeve securely fitted in said hole,.-said sleeve projecting fronrtheinner face of said hub flange and extending in said hole at most as far asthe outerface of said hub flange, said hub flange and said sleevebeing respectively axis of said sleeve, and opening into the outer. faces of said hub flange and sleeve, 21. rectilinear key adapted to fit in said hole for preventing angular displacement of said sleeve with respect to said flange, a spindle adapted to be screwed in said sleeve for fixing the wheel proper to said hub. flange, and means carried by said spindle for locking said key in said hole. p w

:2. In a vehicle wheel, the combination of ahub flange provided with at least one'hole close to its periphery, an inwardly threaded sleeve securely fitted in said hole, said sleeve projecting from-the inner face of saidhub flange-and extending in said hole at most. as far-as. the outer face of said hub flange, said hub flange and said sleeve being respectively provided in their contacting faces. with corn plementary semi-cylindrical grooves: forming together a cylindrical blind hole parallel-to the axis of said sleeve and. opening into the outer facesv of saidhub flange and said sleeve, a cylindrical key adapted to fit in said hole for preventing angular displacement of said sleeve with. respect to said flange; a'spindl'c adapted to be screwed in said: sleeve tor-fixing the wheel proper to said hub flange, and means carried by'saidspi ndle for locking closets its periphery, an inwardly threaded sleeve securely fitted in said hole, said sleeve projecting from the inner face of said hub flange and extending in said hole at most as far as the outer face of said hub flange, said hub flange and said sleeve being respec= tively provided in their contacting faces with complementary semi-cylindrical forming together a cylindrical blind hole parallel to the axis of said sleeve and open= ing into the outer faces of said flange and said sleeve, a cylindrical key adapted to fit in said hole for preventing angular dis lacement of said sleeve with respect to said ange, a spindle whose extremity is screw threaded so as to be screwed in said sleeve for fixing the wheel proper to said hub flange, and a basis on said spindle consisting of an annular collar adapted to be applied against the outer faces of said sleeve and said flange for locking said key in said hole.

In testimony that I claim the foregoing as my invention, I have signed my name.
